Embodiment Construction

[0018] Main purpose of the present invention can be realized by following technical scheme, in conjunction with accompanying drawing, explain as follows:

[0019] Such as figure 1 The steering gear of the active steering system shown in the figure, the driving disc 1 is connected to the peripheral end of the lower shaft of the steering column through the input shaft, the driven disc 2 is connected to the input shaft of the steering gear through the output shaft, and the torque and motion are realized from Transfer from driving disc 1 to driven disc 2. The driver turns the steering wheel to drive the driving disc 1 to rotate, and the driving disc 1 drives the idler 3 to rotate by friction, and the idler 3 also drives the driven disc 2 to rotate by friction, and the driven disc 2 drives the input shaft of the steering gear to rotate, realizing steering control of the vehicle. Among them, in order to reliably transmit the steering input of the driver, there should be sufficient...

Abstract

An active steering transmission device of an active steering system of an automotive front wheel is mounted between a steering wheel and a steering gear and comprises a driving disk (1), a driven disk (2) and an angular transmission ratio regulating device which are disposed in a transmission device housing (8), wherein the driving disk (1) is connected with the steering wheel, the driven disk (2) is connected with an input shaft of the steering gear, and the angular transmission ratio regulating device comprises an alternating current motor (4), a lead screw (5), a nut (6), a connecting rod (9) and an idler gear (3). An output shaft of the alternating current motor (4) is connected with the lead screw (5) which is disposed in the transmission device housing (8), the idler gear (3) is connected with the nut (6) via a bearing, the nut (6) is mounted on the lead screw (5), the connecting rod (9) is arranged on the nut (6), one end of the connecting rod (9) is connected with the nut, and the other end of the connecting rod (9) is disposed in a groove (10) on the transmission device housing (8) corresponding to the lead screw (5). The active steering transmission device is simple in structure, small in mechanism size, convenient to process and low in production cost.

Description

【Technical field】 [0001] The invention relates to an active steering transmission device of an automobile active steering system, in particular to a steering transmission that can steplessly adjust the angular transmission ratio of the steering system so that the vehicle has better handling comfort and active safety. device. 【Background technique】 [0002] The steering system is an important part of the automobile chassis system. Its function is to control the steering wheel to rotate at a certain size and direction according to the rotation of the steering wheel, so as to realize the steering of the vehicle. So the steering system involves the handling stability, active safety and handling comfort of the vehicle. [0003] The angular transmission ratio of most existing steering systems is fixed and non-adjustable, that is, after the design of the steering system is completed, the steering angular transmission ratio is also fixed. However, with the progress and development...
